Hi John I am writing on behalf of Functional gums srl from Italy. Thanks for your valuable comment. US FDA actually never blocked any sales of caffeinated chewing gums they simply raised safety concerns about caffeinated products that could have reached youngsters. This is why our gum has been conceived and developed with the specific focus of helping drivers to stay more awake, alert and concentrated while driving or whatever they are doing. We are sold in several countries in Europe and outside Europe and now willing to expand to the US market. Best regards info@drivegum.com
